Question

find the domain of the function. g(x)=1-2x^2

Answer 1

\[(-\infty,\infty)\]

Answer 2

There are no limitations on g(x)

Answer 3

which means all values of x make sense

Answer 4

I am with Largange's Son

Answer 5

how about g(y)=radical y-10 ?

Answer 6

you have to set this up:

\[y-10\ge0\]

Answer 7

now solve like a normal equation: y-10=0, add 10 to both sides and you get y=10
or in other words, y had to be greater than 10

Answer 8

\[[10,\infty)\]
